Why is it good to be a BIM electrical designer in 2025?

Table of contents

An old topic, but let’s put it here anyway: digitalization and BIM have fundamentally reshaped the entire construction industry. In the past few years, from design through construction and project management, tools, processes, and roles have appeared that a decade ago would have sounded like pure science fiction – and which here in Hungary used to be dismissed with a tired wave of the hand.

It is no coincidence that the demand for BIM electrical designers has also increased: today’s projects are several orders of magnitude more complex than before, require greater precision, and therefore all disciplines – mechanical engineering, architecture, structural engineering, etc. – must work together more closely than ever.

In addition, a new phenomenon has appeared that previously did not really exist:

What does it mean? It means that

• architects instantly see the building electrical requirements that have a major impact on spatial decisions
• and BIM electrical designers from the very beginning have access to architectural modifications that affect their systems.

Alternative electrical distribution strategies can already influence spatial organization during the concept phase, with the result that much better electrical systems can be placed much more effectively in space.

BIM has elevated the electrical discipline from the classic “secondary” role to that of an integrated design partner, where the BIM electrical designer is no longer a solitary “cable drawer” but a unique team member who, through 3D modeling, intelligent data, and clash detection, helps prevent mistakes – saving everyone time, money, and headaches.

Why is it a good decision to move toward BIM-based electrical design?

Because in more and more projects it is a fundamental requirement that electrical and mechanical systems are also designed in a BIM model, and because Hungarian regulations are also pointing in this direction.

If you stick with the old 2D methods, you may miss out on high-quality work, and the projects you do get are not necessarily top-tier – which means you won’t be able to advance much in salary either.

However, if you are a BIM electrical designer, you are one of the most sought-after professionals—precisely because your knowledge is key to modern, sustainable building operations.

What’s wrong with classic electrical design?

Lower pay, slower progress

The real wage level of designers working in 2D tends to stagnate more easily, while companies compete for BIM electrical designers, and this is reflected in higher salaries.

Career ceiling

Using AutoCAD alone in 2025 is basic – a bit like knowing English – so if your skills are limited only to AutoCAD, it is not enough for more serious or international projects today. Knowledge of Revit MEP, Navisworks, or Dynamo, on the other hand, is generally an entry requirement for international work – and also for many advanced domestic BIM integrators or electrical design companies.

Fewer projects, narrowing prospects

Knowledge of BIM greatly determines how many and what type of projects you can participate in as an electrical designer.

➔ On one hand, BIM is a market necessity: although in many smaller-scale segments building information modeling is not yet present (and may never be), government and corporate projects are increasingly BIM-based. The legislative changes and related decree from two years ago made BIM models mandatory for state construction projects from July 2025.

➔ On the other hand, in better places it is an expectation: due to technological development, digitalization, and societal expectations, the demand for non-BIM electrical design is slowly but surely decreasing. Today, in many competitive private-sector projects, an integrated, data-rich BIM model is expected, because 2D is not accurate enough, not informative, and above a certain scale not competitive at all.

➔ Third, BIM is a survival guarantee: in an investment-poor economic climate like the one we live in today, the companies more likely to stay on the scene are those with experienced BIM professionals who can reliably, efficiently, and with higher quality deliver larger-scale projects.

Single source of truth

One of the most important functions of BIM is that you can centrally access classified data. This saves a huge amount of time for everyone: there is no need to search for drawings and specifications in different systems, and the automatic generation and automatic updating of cable schedules, panel schedules, and equipment lists are also solved whenever the design is modified.

Another great blessing of BIM is parametric design: since the system follows predefined rules, light fixtures adapt to illumination requirements, sockets maintain code-compliant layouts, breakers are automatically sized to the loads, and actual cable lengths are built into the model, together with spatial connections. That makes a difference.

Fewer design errors

In BIM, 3D visualization helps make sense of the multi-dimensional puzzle we call a construction project.

Clear orientation makes a big difference: we can prevent errors from cascading like dominoes, and with automated clash detection we can identify spatial conflicts and other potential issues – even ones that would be impossible to detect with traditional 2D coordination processes, such as:

• above-ceiling areas – air diffusers, sprinkler heads, light fixtures
• mechanical pipes vs. air ducts
• cable tray routes running through structural elements
• proper separation distance between water pipes and electrical components.

Beyond preventing clashes, BIM also highlights potential synergies – for example, where systems can conveniently share space, supports, or access points. In addition, BIM shows where there is insufficient installation space around panels, or where data and power cables are not properly separated. Change management is also faster and clearer in BIM: if the architect changes something in the plan, a notification is sent immediately to all disciplines.

Cleaner workflows

BIM breaks down traditional “silos” and makes communication transparent and fast, because instead of linear, sequential tasks, work can take place in parallel, interconnected systems. The connection between models and documentation is two-way, so every modification is automatically updated in schedules, specifications, templates, and so on.

Virtual walkthroughs make it possible to understand electrical designs without having to pore over complex 2D technical drawings. Issues are marked directly in the model, so comments, related solutions, and changes are always visible – no more digging through forwarded emails for hours. Lighting calculations and load analyses are also done in the same data environment as the design, eliminating export-related problems and preventing data loss.

Better design quality

With the help of 3D visualization and performance simulations we can analyze energy consumption, cable sizing, electromagnetic effects, and even simulate emergency power scenarios – things that are practically impossible with traditional methods.

In a project, instead of countless drawings and specification documents, we are essentially building a data-rich, unified data model continuously. Changes automatically propagate through the system, documentation errors disappear, and all the expertise invested in the project is preserved throughout its lifecycle. The models store design decisions, calculations, and coordination solutions, so no data is lost between project phases – which means the BIM model remains an incredibly valuable information base even after the design phase is completed.

Cost and time savings

BIM methodology allows savings for many reasons – primarily because the earlier a problem is solved, the cheaper and easier it is to resolve (or prevent):

• Clash detection identifies errors before construction, reducing costs arising from resource allocation, changes, or schedule delays.
• BIM minimizes waste – cost estimates no longer need to include large reserves for material uncertainty, cable lengths, pipe sizes, and quantities are accurate, there is no need to over-order, precise routing reduces onsite modifications and installation waste, not to mention the other advantages of prefabrication and reduced transport costs.
• Running just the most essential simulations (illumination checks, load distribution analyses, voltage drop calculations) prevents countless delays – which is especially important for critical facilities such as hospitals or data centers. Just think about the consequences of weeks-long delays in obtaining occupancy permits.
• It also benefits logistics: deliveries aligned with installation sequence and precise material quantities significantly reduce handling and onsite storage costs.

4D BIM integrates scheduling with spatial models, showing when and where teams need to work across the entire project. This minimizes downtime, optimizes team organization, and ensures precise installation – preventing electrical work from having to be re-done later because of subsequent construction activities. The as-built model resulting from the BIM project even improves operational efficiency: during maintenance, diagnostics can be performed through quick digital queries rather than hours of onsite inspection.

Costs can also be integrated into the project using 5D BIM software, which – similar to parametric design – provides dynamic, model-based information to improve project cost efficiency.

Discipline optimization also carries synergies on the cost side, in areas such as integrating lighting into architectural elements or coordinating electrical distribution with structural design.

BIM = a better career in electrical design?

In short: yes.

Faster career advancement, better pay, much better working conditions. If you are BIM-certified, it is easier to get into good companies where the quality of work, the standard of projects, and the level of appreciation are much higher.

As a career starter, you will earn more even at the entry level; as a mid-level designer, you can negotiate a better salary; and as a senior designer, you can enjoy truly outstanding pay and serious management opportunities. You will advance more quickly, and your professional knowledge and any management experience you may have gained along the way will make it easier for you to reach international levels.

Stability and work-life balance are also important considerations. As a BIM designer, you can usually work in a hybrid environment, both in the office and at home, with much less need to travel to sites, more predictable days, and a more flexible work schedule, which means a better quality of life.

What skills does a BIM electrical designer need?

• Professional use of Revit – modeling, analysis, design
• Professional fundamentals – understanding the context of the building, how the electrical system fits in with the mechanical systems, building elements, and infrastructure
• Clash detection and coordination – to ensure that the cable does not run through the air duct
• Electrical load calculations – analyses and simulations based on energy requirements and interrelationships
• Understanding BIM workflows – comprehensive knowledge of not only electrical systems, but the logic of the entire project.

Summary

If you are a BIM electrical designer, this is not simply a job, but an entry ticket into the future of the construction industry. Higher salary, more opportunities, stability, and a long-term career.

Those who take the leap today and learn, grow, and develop at the right company will not only be more sought-after professionals in a few years, but will also be at the forefront of the digital construction industry.
